Hello, I am using the tool "raster calculator" using cosine function for one of my raster layers (created from degree format of angle) and I was wondering when I use cosine function on this layer, should I multiply the angle by the transformation (pi/180) inside the function? Should I use cos(name-of-the-raster X pi/180) or just use cos(name-of-the-raster)?. As I said, the layer to be used for this function was created using degree format of angle.
Please advice, any example or link would be appreciated.
Thanks in advance.
